Updated on August 18, 2016

Secure Your Computer Privacy with Freeware

You are concerned about privacy and security while using your PC, but you have no idea what to do to protect your private information safe?

DO NOT Panic! No matter you are new to computers or a geek, the freeware I'm sharing below would probably help you solve common problems. Enjoy!

1. SUPERAntiSpyware Free

Anti-spyware should be the first shield to keep your computer away from malware infection. If your PC is attacked by some malicious software or spyware, privacy will be at risk.

SUPERAntiSpyware is a great free antivirus program that is known to scan and remove spyware, Adware, Malware, Trojans, Dialers, Worms, etc and many other types of threats on your computer. Also, it gives you the options to remove or quarantine them. It offers daily (manual) definition updates, as well as home page hijack protection and customizable scan options. Furthermore, the program includes a repair feature that enables you to restore various settings which are often changed by malware programs, but usually not corrected by simply removing the parasite. This program also can fix folders become shortcuts problems.

2. EASEUS Todo Backup

Backup has been proven to be the most effective way to prevent data loss (look at this hubpage I wrote earlier about Android data loss). Easeus Todo Backup is a free backup and restore utility that can help you the easier way. Like other good backup tools, it will back up your entire system's current state, data, settings, or just what you want it to, including partitions or full disks, and restore your computer in the event of a hard-disk crash or other calamity. EaseUS claims the software has been downloaded and used by over six million home users.

3. Piriform CCleaner

CCleaner is a freeware system optimization tool to clean computer registry and privacy. It removes unused files from your system to speed up your pc and free up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. As you may know, every singer page your browser on your computer is recorded to be history (or "footprint"), including caches, cookies, search history, temporary files and more. With the passage of time, those footprints may take much disk space thus make your computer run slowly. In addition, it records too much of your privacy. By the way, CCleaner is more than a registry clean tool. There are more cool functions to be explored. This blog post has showed how.

4. Recuva

If you are still worried about data loss caused by careless deletion or formatting, then a data rescue tool like Recuva comes right to help. Recuva is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted with human errors, from devices like digital cameras, memory cards, or MP3 players. It even recovers files that have been deleted from your iPod, or from crashes and viruses! It may not only find your recently deleted files, but also many more from months ago.

5. Eraser

Eraser is a secure file deletion tool that allows you to completely remove sensitive data from your hard drive by overwriting it several times with sophisticated algorithms (Gutman, USDoD and others). Simply drag and drop any files and/or folders onto the on-demand eraser, use the convenient Windows Explorer right-click extension or use the built-in scheduler for automated wiping of unused disk space, browser cache files etc.

The app is quite easy to use and secure. Eraser currently supports Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Windows Vista, Windows Server 2008, Windows 7, Windows 8.1, and Windows 10. Alternative free data shredder tools are also available like Freerase, File Shredder, Evidence Nuker etc.

6. TrueCrypt

If you want to create a public space or encrypt a disk to protect those sensitive data. TrueCrypt is an open source encryption tool that can be used for on-the-fly encryption (OTFE). It is distributed without cost and the source code is available. It can create a virtual encrypted disk within a file or encrypt a partition or (under MS Windows except Windows 2000) the entire storage device (pre-boot authentication). TrueCrypt supports a variety of encryption algorithms, including AES-256, Blowfish (448-bit key), CAST5, Serpent, Triple DES, and Twofish. Other features include support for FAT32 or NTFS formatting, hidden volumes, hotkeys for mounting/dismounting and more.

7. Duplicate Cleaner

If you accidentally put your private documents or photos etc in several places of your computer, and don't know how to find them. Then a duplicate finder may be of help. Duplicate Cleaner is such freeware that helps you organize the contents of your home hard drive or corporate network. You'd be surprised just how many redundant or duplicate files you could have forgotten in an obscure documents folder. Duplicate Cleaner will deep scan for all types of files - photos, music, films/video, Word documents, PowerPoint presentations, text files - you name it, if it appears twice on your computer then Duplicate Cleaner will find it. Once these files are found you are provided with helper tools to enable you to select which copies to delete or move. These files can be deleted to the recycle bin, or moved into an archive elsewhere.
